I'm having the same problem, The phone would be working great and then the Internet connection would just go away. I've tried to hard reset it but the problem would just come back. I found out that you could just go to setting and turn the (4g) on then turn it back off, and for some reason that makes the (3g) come back on. I will do more looking around for a solution or an update that would fix this problem.
